1.) Hardiness Zone: Another thing to consider when order plants are the hardiness zones and shipping times. Plants are assigned a hardiness zone depending on the type of climate they can tolerate. Choosing plants that will do well in your zone will allow for greater success. Due to the cold weather, we will hold your plant order for you and ship it once your location is past the last frost warning for the season. This ensures the plants ship at a time that is more suitable for travel and save you the hassle of trying to store them until spring.
